POLE DESCRIPTION
Not all fiberglass poles are
created equal. When we were doing our research of
fiberglass products to create our pike pole line, we discovered
that there are many variables involved. Consequently, it
appeared that most of the competitive products used "stock"
shapes and compositions. We chose to engineer the pole for
the product.
Shape was our first
consideration. We chose not to use any type of "beam"
design since the rigidity changes depending on the orientation
of the cross section. A round pole was the obvious choice
to maintain consistent strength regardless of orientation.
A solid round shape was then considered. The problem with
a solid is the additional weight and cost, especially since most
of the strength comes form the outer portion of the pole and the
material in the center and more weight the strength. That
left a hollow tube as the most viable option.
Most of the poles we have seen
over the years that use a round tube are decent products.
The are relatively strong and the customers like the feel of
them. We discovered that the "off the shelf" poles used
were generally 1.25" in diameter with a 1" hollow center.
This certainly resulted in a light tool with good strength, but
handles were still breaking in the field. An improvement
was needed.

We chose to keep the fairly
standard 1.25" outside diameter since it works well with
existing tool brackets and other mounting systems. To
increase the strength, the wall thickness was increased by
reducing the size of the hollow center to .9". It may not
sound like much, but the wall thickness changed form .125
to.175, a nearly 30% increase. The drawing gives a visual
indication of the impact such a minor change can have. The
greatly increased the strength without adding too much
additional weight.
Further changes were make to the
composition of the FRP (fiber reinforced plastic) material by
the addition of UV stabilizers to mitigate damage from the sun
light. Fire retardants were added to the compound for
obvious reasons.
Since this tube in at the heart
of man of our products, we wanted to make sure it was reliable
enough to carry our name. After testing the samples, we
are very pleased. We think you will be too. |
